[sdiy] Anyone know of a device that does no-added-delay MIDI filtering?

The last nybble comes first - it's little endian.
But that doesn't really make any difference, even if you know what the
status is, you still have to wait for some data.
If you write the code well, you can filter a MIDI stream and output it again
with an additional latency of no more than 1 MIDI byte, 320uS. That's
probably a tiny fraction of the CPU latency on a P600.
